Quenched and tempered steel plate has been developed for industrial uses where a combination of strength and outstanding toughness are necessary such as mining and quarrying, material handling, construction and earthmoving, and offshore fabrication.

The following data is given for each standard: standard number and year, grade, chemical composition and mechanical properties (yield point, tensile strength, notch toughness). When deemed useful, steel type, manufacturing method, thickness of plate, heat treatment and other data are described.

These steel are normally named Duplex stainless steel pipe due to the two phases present in the microstructure. ... Sigma (55Fe 45Cr) can be a major problem when welding thin walled small bore pipe made of super duplex, although it ...

Lifetime Estimation of Chain Plates for Floodgates Working ...

Numerical estimation of lifetime of chain plates made of 45Cr high strength steel for floodgates working in seawater has been performed by considering fatigue-creep crack initiation and hydrogen assisted crack propagation at the plate. The computational model has been validated by some related experiments on the material. First, tensile test results for the material of chain plates used for 20 ...Authors: Hak Jin Song · Sun Jong Jon · Gi Chol Yang · Nam Chol KimAffiliation: Northeastern UniversityAbout: Hydrogen embrittlement · Stress corrosion cracking · Stress concentration
